I have a project that I do with my Art 2 class that is very popular called a
"weave" drawing. I have the kids find two black and white pictures that have
a commnon thread or theme, such as fisherman/fish(trout,etc.) tools/building,
etc. Try not to have two pictures of faces, or the same kind of objects as
this will get confusing. sometimes I tell them to look for a predominately
dark picture and a predominent light picture.

Have them take the best picture/photo and cut it into 1" strips vertically.
Tape it at the top after reassembling it and put it on some blank paper as a
backing. Next cut the other picture into 1" strips horizontally. Weave these
strips in and out with the vertical picture untill it is complete. Tighten
the strips so that there are no gaps and they are square with each other.
Tape down the edges so that it won't move. Look at the resulting picture and
perhaps remove a sqaure if it will improve the identification of the image (
use an exacto knife). We do this so that you can tell what they are but still
very much woven together.

Count how many square are down and across. depending on how many there are
you will make a sketch of each square on newsprint. We usually go 1" to 3".
When they are skeching the little square they are using the grid lines to help
in making the small picture into a bigger one. They must use ratios and size
development.

After the sketch of what's happening in each square is complete. Graphite the
back and lightly transfer the image to a good white drawing paper ( I use
strathmore 400). Next we discuss the use of drawing tools such as q-tips.,
tortillions, paper towels,cotton balls fingers and different drawing pencils
to try and create a gradation of black to white having many, many levels of
grey, some of these we don't even use a pencil just rubbing tools.

They then begin to render each square until the picture is complete. We
discuss abstraction and cubism a little here so that they can see that they
can still see the objects, but they have been distorted. Their drawing skills
become very good and they can usually draw things that would be too
complicated normally, with out the weave distortion. I have also had them
weave one color and one black and white, then use color pencil. This is best
with a group that have some drawing background and observation training but
they do love it and are quite proud of the results. Too bad you can't see the
slides that I have because they show this very easily and you can see some
very good drawings.
